Inmates are kept isolated and housed in
cells that have a set of three steel doors. For 90 minutes a day, they are transported to a large cage for exercise; during this time, cells are searched for
contraband or illegal items. Prisoners at Black Dolphin are kept under 24-hour supervision; they are not permitted to rest or sit on their bunks from the time they are awoken until it is time to sleep again, a span of about 16 hours. Every 15 minutes, a guard makes rounds to ensure inmates are complying with the rules. The prisoners are fed soup four times a day.
he prisoners are only allowed books, newspapers, and a radio (which is their only link to the outside world). When prison officers make a command to the inmates, they must respond with the words "yes, sir"
